摘要
Ten secondary metabolites (1-10) including a new 4-hydroxycinnamic acid derivatives, methyl 2-{(E)-2-[4-(formyloxy) phenyl] ethenyl}-4methyl-3-oxopentanoate (1), and nine known compounds (2-10) were isolated from an EtOAc extract derived from a solid rice medium of endophytic fungal strain Pyronema sp. (A2-1 & D1-2). Their structures were elucidated from NMR and HRMS data. All the compounds were tested for antibacterial activity against Mycobacterium marinum ATCCBAA-535. Compounds 1, 8 and 9 exhibited moderate antibiotic activity with IC50 of 64, 43 and 32 mu M, respectively.
